Overall the app is easy to use. Getting a quick popup when starting to type in a few letters is great. Example: "ban" immediately brings up small banana, large banana, etc. ( or is this Google?). Calorie output is great, but has a flaw that the developers should be able to fix. When making a mistake about, for instance, walking, it's impossible to zero it out. Even uninstalling and reinstalling didn't work. The scanner functionality for packaged foods is brilliant, but also has a frequent flaw. Often the calorie count that pops up contradicts the label. For instance, Hafi lingonberry preserve shows 34 calories vs 30 calories shown on the jar. This happens again and again for other foods. This should also be easy to fix. Overall bravo!
